In Response To: NG Gammon percent vs Regular BG gammons (KenB)

I suspect your rollouts allow doubles on the first move which would distort both rollouts significantly. Here's GNU Money for the opening position for comparison. Opener wins fewer games and gammons. This rollout does not allow doubles on the next roll.

The score (after 0 games) is: GNU_bg 0, user 0

Move number 3: GNU_bg to play 61
